Are Freemasons expected to prefer fellow Masons
at the expense of others in giving jobs, promotions, contracts and the like?

Absolutely not. That would be a misuse of membership
and subject to Masonic discipline. On his entry into Freemasonry each candidate
states unequivocally that he expects no material gain from his membership.

At various stages during the three ceremonies
of his admission and when he is presented with a certificate from Grand Lodge
that the admission ceremonies have been completed, he is forcefully reminded
that attempts to gain preferment or material gain for himself or others is
a misuse of membership which will not be tolerated.

The Book of Constitutions, which every candidate
receives, contains strict rules governing abuse of membership which can result
in penalties varying from temporary suspension to expulsion.
